To many people, Thatcham Research are synonymous with vehicle security. Rightly so, given the centre’s contribution to an impressive reduction in UK vehicle crime since the mid-90’s.

Thatcham’s vehicle security team was established in 1992, with the primary aim of stemming the explosion in vehicle crime, which at the time was proving of great concern to the insurance industry.

Today recorded theft of vehicles is less than 100,000 cases per year down, from 620,000 at its height. Whilst many organisations can claim credit including vehicle manufacturers, UK law enforcement and government, Thatcham have been instrumental in driving up standards in both factory fit and aftermarket vehicle security installations and our security testing regime is considered to be one of the most rigorous in the world, acting as a model for crime prevention efforts internationally.

Over the past two decades, Thatcham have subjected almost every new vehicle destined for UK roads to a New Vehicle Security Assessment, (NVSA). In the case of cars and LCVs, the results from the Thatcham NVSA go forward to the insurance group rating panel where, depending on performance, they can affect a vehicle’s grouping by up to 2 groups. Find out how your vehicle performs in our 'My Vehicle' ratings section.

Thatcham's security team also carry out extensive testing on a wide range of original fit and aftermarket security equipment covering the following vehicle types

  • Passenger cars
  • Light Commercial Vehicles
  • Heavy Goods Vehicles
  • Motorcycles
  • Agricultural and construction machinery

The Thatcham National Security Listing details all security systems that have proved to be compliant with 'The British Insurance Industry's Criteria for Vehicle Security' and is sectioned by vehicle type for your convenience.

Thatcham's security engineers travel throughout the world continuing to analyse current theft methods and techniques that are used to break into and steal vehicles. This information is then used to update the criteria, against which new vehicles are assessed, to combat new theft techniques and to update vehicle manufacturers, enabling them to improve on potential weak points in a vehicle’s security design before they are launched in the UK. This work has helped us to build strong working relationships globally with vehicle manufacturers, importers, the police, insurance companies, governmental organisations and after-market security system manufacturers and suppliers.
